I was dissapointed with the potency of dutch passion and happy with female seeds. I have also had a problem with the germination rate of female seeds but have since discovered the problem was my own doing. Sativa seeds take a long time to pop and I wasn't patient enough. I store my seeds out in the garage and then warm them at eighty degrees between wet paper towels, once they pop I put them in soil filled cups. Now my germination rate is aconsistant 90 plus percent.
